Application filed October 19, 1916, Serial No. 126,469. I Renewed March 1, 1919; Serial No. 280,16.

To all whom it may concern:

Be it known that I, ISAAC ROSENFIELD, a citizen of the United States, and a resident of Anaconda, in the county of Deerlodge and State of Montana, have invented a new and Improved Resilient Wheel, of which the following is a full, clear, and exact description.

This invention relates to resilient Wheels and has for an object to provide an improved construction which is simple, strong and adapted for use with vehicles of any kind.

Another object in view is to provide a resilient wheelin which rubber or other similar cushion members areutilized and the resiliency or spring of bowed metallic spokes is utilized for producing the desired effect.-

A still further object in view is to provide the combined use of a rubber or other cushioning member and resilient spokes so arranged that the rubber cushioning. member will act for taking up slight jolts-or jars and all vibration and the metallic spokes will act in conjunction with the rubber cushioning member for taking up the more or less heavy or great jars, thus producing a very resilient structure under ordinary circumstances and a much stiffer resilient structure for special circumstances.

In the accompanying drawings Figure 1 is a s1de view partly 1n section of a wheel embodying the invention. 32? Fig. 2 is a sectional view through Fig. 1

on line 2-2.

Fig. 3 is a sectional view through Fig. 1 on line 33. I,

Fig. 4 is a perspective view of one of the hub cushioning blocks embodying certain features of the invention.

' Fig. 5'is a perspective view of one form of the rim cushioning blocks embodying certain features of the invention.

Referring to the accompanying drawings by numerals, 1 indicates a metallic rim which presents an I-beam structure in cross section, as is clearly shown in Fig. 3, where by there are" produced annular grooves 2 and 3, respectively, groove 2 being designed to receive the outer band or tire 4 of rub her or other suitable material. The groove 3 is designed to reccivevarious bumper or cushioning blocks 5. These blocks are formed of any suitable resilient material, preferably rubber, and are arranged with of radial lugs 7. An aperture 8 is provided in each of the cushioning members 5 for re-.

ceiving one of the binding bolts 9 passing through the clamping rings 10 and 11. The bolts 9 and rings 10 and 11 are intended merely for holding the cushioning blocks or members 5 in position so that the same may act as cushioning members for the various spokes l2 and 13 hereinafter further olescribed.

The hub 1 1 is provided with a flange 15 upon which rest a plurality of cushionin blocks 16 held in place by clamping bolts 1% and side rings 18 and 19. The rings 18 and 19 are rigidly secured to the annular flange 15 by any suitable number of bolts 20, thus forming an annular groove or channel for the various cushioning blocks 16 which are made from rubber or other resilient marial.

A shown in Fig. 1, the cushioning blocks- 5 are arranged in pairs, each pair being opposite a single block 16 on the hub so that the various spokes 12 and 13 may extend from one set of blocks 5 to one block 16. It will be observed that there are shown two spokes l2 and two spokes 13 associated with each blocks 16, though a greater number might be used if desired. Between each set of blocks 16 are positioned the ends of the respective spokes 21 and 22, there being preferably two spokes 21 and two spokes 22 between each block 16. Lock nuts 25 are arranged on the various spokes 21 and 22 and press against the cushioning blocks a so that the spokes are rigidly clamped to.

The inner or hub end of the spokes 21 and 22 are snugly arranged in sockets 26 with their ends normally spaced a short distance from the bottom of the sockets so that when rim 1 is moved inwardly for a short distance the resistance to such movement is caused by the-respective spokes 12 and 13 and the cushioning blocks 5 and 16. If the continues, then the hub end of the spokes 21 and 22 will press against the hub 14 and resiliently resist further movement of the rim by reasonof the fact that the spokes 21 and 22 are provided with bowed portions 27.

It will thus be seen that the first and smaller shocks and vibration are taken up by the spokes 12 and 13 which are bowed movement of the rim 1 toward the hub 14 as shown in Fig. l, and by the cushioning blocks 5 and l6, while the greater shocks are absorbed by the spokes 21 and 22 which are of resilient material and are preferably formed with several bowed 'portioflflifl3 shown in Fig.1." The bowing of a1l,of ,.--thb.

spokes is in a plane preferably .atfri ht angles to the axis-,ofi the wheel; Thespo' -12 and 13 snugly eat-end into therubber' blocks 5 and '16 *and are caused to press against these blocks by reasonpf-thehiits.

28 actin on plates 29 and 3Q,":resp etiv 1yi Both en s of spokes 12 and were threaded so that these spokes may maintain the blocks 5 and 16 under a continuous compression. It is to be noted that part of the first shock of the wheel will be taken up by the tire and the remaining part taken up by blocks members arranged exteriorly thereof, a plurality of spokes extending from said cushioning members, a cushioning member arranged at the outer ends of said spokes, means arranged on said spokes for giving said cushioning members a tendency to move apart, and a rim surrounding said outer cushioning members.

2. A wheel comprising a rim, a hub, a plurality of sets of spokes, a plurality of cushioning members arranged adjacent the rim, a plurality of cushioning members arranged adjacent the hub, the spokes of alternate sets being spaced, said spaced spokes being rigidly connected with said cushioning members and slidingly engaging said hub so that there must be an appreciable movement of the hub toward the rim before the spaced spokes will act, and lneans arranged on the remaining spokes for maintaining them under tension, whereby the said remaining spokes and said cushioning members will take up the first strain or movement on said rim and said spaced spokes will act as auxiliary supports for the rim.

3. In a resilient wheel of the character able nuts on the spokes, and means actin described, a hub, a rubber cushioning stru c- .f

ture surrounding aidhub, arim, a rubberl',

cushioning structure arranged 'interiorly of. said rim, a plurality of principal spoke'sf -f having their opposite ends projecting into '60; the resilient structure on the hub and the" resilient structure interiorly of the rim a" plate arranged adjacent each end of said.

"principal spokes, means on each of said? spokes for pressing saidi platesagainst said. respective cushioning. structures so that the strain will be communicated from one cush-v ioning structure to the other through said means on the principal spokes for placing said blocks under compression whereby motion will be communicated from one block to the other through said spokes, said auxiliary spokes and said principal spokes being formed with bowed portions intermediate their length, said bowed portions being resilient.

5. In a wheel of the character described, a hub, a plurality of rubber cushioning blocks arranged on said hub, a rim, a plurality of rubber cushioning blocks arranged on said rim, resilient metallic spokes con? necting the blocks on the hub with the} 95 blocks on the rim, tensioning means 03 the spokes for pressing against said block said tensioning means comprising plates fitting against said rubber blocks and adjuston said cushioning blocks on said rim an engaging said hub for taking up excessive strains on said rim.

In testimony whereof I have signed myname tothis specification in the presence of 105 two subscribing witnesses.
